Coastal flood hazard maps for the United Kingdom model three distinct probability scenarios. The data likely contains flood extents and depths for high (10-year), medium (200-year), and low (1000-year) return periods, plus a 200-year event incorporating UKCP09 high-emissions climate projections for the 2080s. These maps were produced by the Government Digital Service for consistency with Scottish Planning Policy.
Use Cases
- Assess flood risk for coastal development planning based on the described return period scenarios.
- Model potential future flood impacts under climate change based on the UKCP09 high emissions 2080s projection.
- Validate hydrodynamic flood models by comparing predicted extents with the mapped high-probability (10-year) events.
- Create vulnerability indices for coastal communities based on the available flood depth and extent layers.
Strengths
- Includes a specific climate change scenario defined by UKCP09 2080 high emissions 95%ile predictions.
- Covers three distinct probability levels (10-year, 200-year, 1000-year return periods) for risk stratification.
- Maps are aligned with official Scottish Planning Policy return period standards.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Last update date is unknown; freshness unverified.
- Row count and spatial resolution are unknown, which may limit suitability assessment.
